DONALD ELDER, OF ONEH'UNGA, NEW ZEALAND.

APPARATUS FOR WATERING AREAS OIF LAND.

Application filed January 5, 1922, Serial No. 527,259, and in NewZealand November 8, 1920.

This invention relates to means employed in watering areas ot land andhas for its object the provision ol improved sprayer whereby areas otland of any shape can be watered evenly and thoroughly.

The. sprayer comprises a casing containing a turbine, carried by ahollow fitting and capable oit revolving about a vertical pipepreferably fixedto a stand or base and adapted to be connected with theWater discharge outlet of a regulator of the type disclosed in myco-pending application, Se-

rial Number 577,266 ,tiled July 24, 1922.

The water passes from the vertical pipe through the hollow fitting andthe casing to an outlet provided with a nozzle. In passing through thecasing, the water drives the turbine, the shaft ot which is geared witha stationary worm wheel on the vertical pipe or on a fitting thereon,whereby the turbine is utilized to give 'rotary motion to the sprayerabout the vertical pipe. The rot-ary motion can be continuous in the onedirec tion or be suoli that the sprayer will make a 'full revolutionilrstin one direction and then a tull revolution in the reversedirection. or said sprayer can be caused to operate backwards andforwards through any desired portion o't a circle.

In order to accommodate the sprayer or rather the jet ot water from sameto arcas having irregularoutlines or boundaries, a nozzle containing acocl is employed the discharge et said nozzle having projectingtherefrom a rigid arm kept in contact with a stationary regulating plateon the upper end ot the vertical pipe. This plate is given a shape oroutline which corresponds with that ot the area oit land to be watered.As the sprayer rotates about the vertical pipe, the arm ot' lthe nozzleis dragged along the edge ot the regulating plate and rides over theprojections on and enters the depressions in the latter, whereby thedischarge end ot' the nozzle is raised and lowered to regulate the throwot' water to the outline ot the area, and also to regulate the volume otwater issuing from the nozzle.

he invention will now be more particularly described in conjunction withthe aocompanying Adrawings wherein ,Figure 1 is an elevation (broken) ofthe sprayer. l

Figure 2 is a plan view ot same.

Figure 3 is a sectional plan view taken on the line A--A, Figure 1.

Figure 41 is an inverted plan view of portion ot the reversing clutchactuating mechanism.

Figure 5 is a part plan view showing the sprayer' constructed so as torotate cont-inuously in the one direction, while Figures 6 and 7 are aplan view and a cross sectional view respectively of the re versingclutch.

Figure 8 illustrates a plate for regulating the volume of water and thealtitude of the stream of water when watering an area having a shapesimilar to that of the plate.

Referring to the drawing in detail the vertical pipe 105 whichpreferably is fitted in a suitable stand or base and receives water troma regulator of the type disclosed in my copending application hasscrewed in its upper end a tube `106 closed at its upper end upon whichis a vertical stud 106.

it hollow fitting 115 having in its upper end an opening'whieh fits thestud 106, and in its lower end an opening which fits the tube 106 is`rotatable about the latter, an annular space 107 being left around thetube 106.

The tube 106` contains one or more ports 108 which open into the annularspace 107.

lVater from the pipe 105 passes through the tube 106, ports 108. andannular space 107 into the branch 109 which is connected 'with the inlet110 ol" the casing 111, so that oi the regulating plate 116, heldstationary` on the stud 106u at the upper end of the tube 106.

The plate 11G has an outline shaped to correspond with the outline ofthe area or the portion thereof to be watered and as the sprayer isrotated about the pipe 105, the arm 114 is forced by the spring 117 intoany depressions or recesses there may be in the edge ot' the plate 116,the result ot which is that the mouthpiece 114a ot the nozzle v113 isdepressed and causes the cock gull to reduce the volume water if' iinpj'from the mouthpiece and at the saine time to shorten the throw i thewater 'from the nozzle.

As the arm 1111v rides over any projection on the plate edge themouthpiece 1141" ot the nozzle 113 is elevated which allows the volumeo1 vater to be increased and causes the thro v et the water to belengthened.

3y these ineans both the volume and the throw ot water from the nozzle113 are renuiated at all times to keep within the linut ot the areabeing treated and to evenly waterl the whole area providing that a plate11i having; an outline correspendingl with tl at ot he area being;treated is provided tor the aini 11e to work against.

The turbine contained in the casing` 111 comprises z vertical dise 118having a boss or hub 118?L keyed on the shatt 119.

Projecting; at r' it angles iti-oui the f 118 and a short distance Ytromthe et thereof is a circular wall 120 whereby an annular space 121surrounding the boss or hub 118a is provided.

:The turbine blades are litted to the disc 118 and circular wall, 120,outside the latter, said blades being` curved to meet the waterentering)` the casing 111 through the inlet- 110.

Ports 123'tlirough the wall 120, between theblad open into the annularspace 121 enabling water to enter the latter.

vWater o'i eircring the casing 111 through the inlet 11() fills thespace 121 a'ttcr which incoming wat fr can only escape by way oit theoutlet 112, and in doing so acts on the blades 122 and drives theturbine in the dircetion indicated by the arrow in Figure 1.

@nene end ot the turbine shaft 119 is keyed a worm 121i which drives aworni wheel 125 in turn keyed on one end ot a shatt 126 mounted inbearings on a bracket 2T carried by the casing 111.

0nthe other end oif this shaft 126 is keyed a bevel whee 12S whichmeshes with two bevel wheels 129, 130 loosely niounted on a shatt 131supported in bearings on the b 'aclet 127, at right angles to the .hatt126.

A clutch 132 feathered on the shatt 131 so to be slidable thereon butalways rotatin` therewith provided at each end with teeth 132a and isoi? such i ,tengjgth hat when the teeth at one end e enjcagiei in corresl'londi'iliy "formed teeth one oi he whrrlr; 129 130, the teeth at theother cud are clear ot siii'iilar teeth ou the other ot said wheelsI129v St?.

rEhe teeth 152n at one end ot the clutch 132 bcingr engaged in the teethot one of the wheels 129-130, the engaged wheel is locked on and drivesthe shaft 131, the effect of which is that the worm 133 working in thestationary worm wheel 134 causes the casing 111 and tting 115 with theyparts carried thereon to travel around the pipe 105. If it is desiredthat the sprayer shall make a full vturn in one direction, and then a.full turn in the opposite direction, only one pin or peg 136 is placedin the wheel 134. When the clutch arm 138 strikes the pin or peg.

136 the vertical shaft 137 is given a partial turning movement and theclutch engaging arm 139 is moved towards the opposite end of the clutch132 until it comes in contactV the clutch 132 from the wheel 129 or thewheel 130 the point of the arm 141 clears the point of the projection142 whereupon the latter springs forward and acting against the side ofthe arm 141 gives further turning movement tothe vertical shaft 137,`

which results in the upper arm 1.39 forcing the clutch 132 intoengagement with the opposite of the wheels 129-130 from which it waswithdrawn, whereby the shaft 131 is caused to rotate in the reversedirection and the sprayer is caused to travel about the pipe in thereverse direction to which 1t didjust previously. y

TVhcn however the sprayer is required to operate backwards and forwardsthrough a given portion of a circle, two pins or pegs 136 are used.These ai'e placed in the wheel 134 the necessary distance apart and eachtime the arm 138 strikes a. pin or peg 136, a reversal of the travel ofthe sprayer about the pipe is effected.

The sprayer' constructed as shown inthe drawing can be caused to rotatecontinuously in the onedirection by locking the clutch 132 in whicheverof the wheels 129-130 it is desired and not inserting any pins or pegs13G in the wheel 134;

During the whole of the spraying operi.- tions tht` altitude of themouthpiece 114EL of the nozzle 113 is being adjusted to lengthen orshorten the throw of the water according to the outline of the'area bythe arm 114 rising to pass over projections on and being lowered byentering depressions in the plate 11G, said depressions being providedat points corresponding with portions projecting from hollows in theoutline of the arear boundaries are to be watered, a jointed nozzle neednot be used, as an ordinary rigid nozzle will serve as well.
